Airtac SAIJ100 Adjustable Cylinder SAIJ100X40-10
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X40-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 40mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X40-10
The AirTAC SAIJ100X40-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 3927N of push force at 0.5 MPa. It features a carbon steel piston rod with an M20x1.5 thread and uses a PT tapered G1/2 port. By integrating an external 10mm adjusting stopper, this model creates a precise 30-40mm usable travel window from its 40mm nominal stroke.
This adjustable design allows you to fine-tune the retract end position during commissioning without swapping out the entire cylinder. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE or DMSE switches if a magnet is specified later. It supports a reduced set of ISO 15552 mountings—Basic, FA, LB, TC, FTC, TCM1, and TCM2—omitting FB, CA, CB, and CR.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X40-10 Is Used
Short-Stroke Clamping
Dial in the exact 30-40mm clamping depth on variable-thickness parts without adding external stopper blocks to the fixture.
End-Position Trimming
Fine-tune the retract position during machine commissioning to prevent over-travel, using the rear screw to absorb setup tolerances.
Product Changeover
Quickly adjust the stroke end by up to 10mm when switching between slightly different product sizes on the same production line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X40-10 the Right Cylinder?
Choose this 100mm bore when an 80mm cylinder (providing 2513N push at 0.5 MPa) lacks the necessary thrust, but before stepping up to a 125mm bore (6136N). The 10mm adjustment range is ideal for applications requiring a short, variable end-stop, giving you a 30-40mm travel window to dial in during machine setup rather than relying on a fixed-stroke SAI cylinder.
Because the nominal stroke is only 40mm, side-load risks are minimal, though the substantial 25mm rod and M20x1.5 thread handle high axial loads well. Note that the rear adjuster acts purely as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series. To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 100mm bore, 40mm stroke, PT port, and desired mounting.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ100 Adjustable Cylinder SAIJ100X40-10 FAQ
At a 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from 40mm down to 30mm. It allows precise end-position tuning at commissioning, though it does not lock the load without continuous air pressure.
